FTP connections do not load directories

I have a sub-server which is at on a private ip. when trying to FTP to the sub server or even the ip address it will not seem to load the directory even though it accepts the user/pass:

Status:  Connecting to 98.142.218.60:21...
Status:   Connection established, waiting for welcome message...
Response:    220 FTP Server ready.
Command:  USER wellcorprx
Response:   331 Password required for wellcorprx
Command:   PASS **********
Response:   230 User wellcorprx logged in
Command:  OPTS UTF8 ON
Response:  200 UTF8 set to on
Status:  Connected
Status:   Retrieving directory listing...
Command:    PWD
Response:   257 "/" is the current directory
Command: TYPE I

Command:  PASV
Response:  227 Entering Passive Mode (98,142,218,60,209,254).
Command: MLSD

I am not sure how to troubleshoot this. Please advise. I appreciate it! Scott
